The Effects of AFO Heel Height and Stiffness on Gait (NCT04800484)

๐ŸŸข Recruiting Observational / Diagnostic โš™๏ธ Medical Device Protocol Sponsor: University of Iowa

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

The proposed study evaluates the effect of ankle foot orthosis (AFO) heel height and stiffness on the forces and motion of the lower limb during over-ground walking in individuals who use an AFO for daily walking. Previous studies suggest that heel height and stiffness effect limb loading, but these data and the analysis techniques applied are limited. In this study, heel cushions with different height and stiffness's (4 conditions) will be placed in participants shoes and they will walk at controlled and self-selected speeds. Participants will also walk with their AFO as configured prior to enrollment, and with no AFO if possible. The proposed study will provide evidence that can be used by clinicians and researchers to align braces that most effectively improve function during every-day walking.
